Just months after boasting about her single status, the Nashville star is back in the arms of her Ukranian heavyweight boxer beau, Wladimir Klitschko.

The pair made no secret of their rekindled romance as they smooched in the fan-packed stands of the American Airlines Arena in in Miami, Fla., as the hometown Heat took on the Charlotte Bobcats in a Sunday matchup. Between packing on the PDA, Panettiere, 23, and Klitschko, 37, cheered on the Heat to their 26th-straight win.

Though the pair called it quits back in May 2011 — blaming long distance for dissolving their two-year relationship — they reunited this January, just a month after Panettiere parted ways with her boyfriend of more than a year, New York Jets wide receiver Scotty McKnight.

Less than a week after claiming she was without a man at the 2013 Golden Globes, Panettiere was spotted cozying up with Klitschko while halfway across the world in Dubai.

“She was shopping at Mall of The Emirates, and Wlad was with her,” an eyewitness told Celebuzz. “Hayden even leaned in to peck him [but] more like nuzzled him, because you can’t really kiss in public in Dubai. They’re definitely more than friends.”

After the Heat they brought in Miami, it seems they are all for flaunting their affections now.
